Abstract

Dispersion precompensation with a prism sequence and a third-order dispersion
mirror resulted in negligible broadening of sub-10-fs pulses at subwavelength
spot sizes when the pulses were focused with microscope objectives and moderate
apertures. At larger apertures, lens chromaticity and spherical aberration
led to an effective pulse broadening of up to 1.3×, depending on the aperture size and the detector position. The
data suggest that intensities exceeding 1014W/cm2 can be produced directly from femtosecond pulse oscillators.
